PROCESS OF TREATING FUR TO PREPARE lT FOR FELTING.

SPECIFICATION forming part of Letters Patent No. 339,353, dated April 6,1886.

Serial No. 186,481. (No specimens.)

To all whom it may concern.-

Be it known that we, EDMUND TWEEDY, a resident of the town of Danbury, in the county of Fairfield and State of Connecticut, and

5 HENRY L. Bnnvoonr and ISAIAH L. ROBERTS,

residents of the city of Brooklyn, county of Kings, and State of New York, and all citizens of the United States, have invented a new and useful Improvement in Processes for Treating Fur to Prepare it for Felting, of which the following is a specification.

\Ve have already applied for patents which describe the treatment of fur with prepared oxidizing fumes, in order to put the fur in condition for subsequent felting. We have found that the period of time necessary for producing oxidation can be greatly reduced if moisture is present on the fur when it is submitted to the prepared fumes, and we have 20 filed an application of even date with this, in which is described the process of treating the for with oxidizing fumes or vapor, such as nitric or nitrous fumes oommingled or mixed with aqueous vapor.

Our present invention relates to another method or process of producing the same result; and it consists in dampening the for while on the skins, either by dipping them in water or throwing water or a spray of water upon it, or submitting it to contact with wet substances, or making the fur damp in any way, and then, while in the dampened condi ti'on, submitting it to the action of the oxidizing-vapors, substantially as described in our former applications.

Our theory is, that the oxidizing vapors or fumes operate more rapidly and more effectively upon the fur fibers when they are moist or damp. If no moisture is present during the fuming operation, except such as is derived 0 from the air, the fuming is a long operation. WVhether our theory is correct or not, advantageous results can be obtained by following the directions given in this specification. No specific amounts of moisture are necessary; but 5 it is advisable to thoroughly dampen the fur upon the skins, while at the same time it is not advantageous to so wet it that it becomes matted. v

\Vhat we claim, and desire to secure by Let- 5o ters Patent, is-

As an improvement in the art of treating for with prepared oxidizing fumes or vapors to adapt it for felting, the process which consists in first dampening the fur with water and 55 then submitting it in the damp condition to the action of prepared oxidizing fumes or vapors, siibstantially as described.
